Superdirt Made Lost Amazon Cities Possible
nationalgeographic ^

Posted on 11/30/2008 3:36:23 PM PST by JoeProBono

Centuries-old European explorers' tales of lost cities in the Amazon have long been dismissed by scholars, in part because the region is too infertile to feed a sprawling civilization. But new discoveries support the idea of an ancient Amazonian urban network—and ingeniously engineered soil may have made it all possible.

Now scientists are trying to recreate the recipe for the apparently human-made supersoil, which still covers up to 10 percent of the Amazon Basin. Key ingredients included of dirt, charcoal, pottery, human excrement and other waste.

If recreated, the engineered soil could feed the hungry and may even help fight global warming, experts suggest.

The artical identified itself as junk science as soon as it began parroting the “Global warming” line.

They used the super rich natural compost piles found in their swamps and low lands!

You’d better be careful if you’re going to mix human waste in with the soil you grow food in. All kinds of nasty diseases are possible, including cholera.

There may be a reason these cities were empty when the Conquistadors found them.

Oh goody ... Let us recreate our civilization after the Amazon tribes’. They are to be admired and imitated. EVERYBODY! Off with your pants and into the nearest river. Wahhooooooo!

This soil type was described briefly in the book 1941 by Charles C. Mann.
Seems that many indigenous people still farm on the soil to this day.
Quite an amazing legacy.

TERRA PRETA/LINK.

"Terra Preta de Indio" (Amazonian Dark Earths, earlier also called “Terra Preta do Indio” or Indian Black Earth) is the local name for certain dark earths in the Brazilian Amazon region. These dark earths occur, however, in several countries in South America (Brazil, Ecuador and Peru) and possibly beyond.

As ecologically rich as the rainforest may appear, the soil it stands in is unsuited to farming – largely a result of the incessant rain washing away all nutrients. But those pockets of soil that are Terra Preta, are suitable for farming and thus form an out of place patch of fertility in an otherwise harsh environment. In fact, it has the ability to maintain nutrient levels over hundreds of years. According to Bruno Glaser, a chemist at the University of Bayreuth, "If you read the textbooks, it shouldn't be there." According to a study led by Dirse Kern of the Museu Goeldi in Belem, Terra Preta is "not associated with a particular parent soil type or environmental condition", suggesting it was not produced by natural processes...

That does not impress. If you want to see superdirt, go to Ukraine. The top soil looks like licorice. In WW-2 the Germans dug up about ten square miles of Ukrainian top soil to ship back to Germany.

The Ukrainians were not happy.

I have seen wheat fields from the train that are so large they disappear over the horizon. Quite a sight.
